Abstract: A design structure for capacitor having a suitably large value for decoupling applications is formed in a trench defined by isolation structures such as recessed isolation or shallow trench isolation. The capacitor provides a contact area coextensive with an active area and can be reliably formed individually or in small numbers. Plate contacts are preferably made through implanted regions extending to or between dopant diffused regions forming a capacitor plate. The capacitor can be formed by a process subsequent to formation of isolation structures such that preferred soft mask processes can be used to form the isolation structures and process commonality and compatibility constraint are avoided while the capacitor forming processes can be performed in common with processing for other structures.

Abstract: An electrical fuse and a first dielectric layer thereupon are formed on a semiconductor substrate. Self-assembling block copolymers containing two or more different polymeric block components are applied into a recessed region surrounded by a dielectric template layer. The self-assembling block copolymers are then annealed to form a pattern of multiple circles having a sublithographic diameter. The pattern of multiple circles is transferred into the first dielectric layer by a reactive ion etch, wherein the portion of the first dielectric layer above the fuselink has a honeycomb pattern comprising multiple circular cylindrical holes. A second dielectric layer is formed over the circular cylindrical holes by a non-conformal chemical vapor deposition and sublithographic cavities are formed on the fuselink. The sublithographic cavities provide enhanced thermal insulation relative to dielectric materials to the fuselink so that the electrical fuse may be programmed with less programming current.

The first end of the fuse link is connected to the anode and the second end of the fuse link opposite the first end is connected to the cathode. This structure also includes a first silicide layer on the anode and the fuse link and a second silicide layer, different than the first silicide layer, on the cathode. The difference between the first silicide layer and the second silicide layer causes an enhanced flux divergence region at the second end of the fuse link.

Abstract: Manufacturing yield of integrated circuits having differentiated areas such as array and support areas of a memory is improved by reducing height/step height difference between structures in the respective differentiated areas and is particularly effective in conjunction with top-oxide-early (TOE) and top-oxide-late processes. A novel planarization technique avoids damage of active devices, isolation structures and the like due to scratching, chipping or dishing which is particularly effective to improve manufacturing yield using TON processes and also using TOE and TOL processes when average height/step height is substantially equalized. Alternative mask materials such as polysilicon may also be used to simplify and/or improve control of processes.

Abstract: A fuse structure comprises a cavity interposed between a substrate and a fuse material layer. The cavity is not formed at a sidewall of the fuse material layer, or at a surface of the fuse material layer opposite the substrate. A void may be formed interposed between the substrate and the fuse material layer while using a self-aligned etching method, when the fuse material layer comprises lobed ends and a narrower middle region. The void is separated by a pair of sacrificial layer pedestals that support the fuse material layer. The void is encapsulated to form the cavity by using an encapsulating dielectric layer. Alternatively, a block mask may be used when forming the void interposed between the substrate and the fuse material layer.
